Hi there, it looks the format of data that you construct through Postman is not what Stripe API expects

This is what you passed

        "price_1Nb445I2rfN87qVGKpiCIGNB",
        "1"
      ]

but if you look at the API reference (https://stripe.com/docs/api/customer_portal/configuration#portal_configuration_object-features-subscription_update-default_allowed_updates) the allowed values are price, quantity and promotion_code

Stripe API reference – The portal configuration object – curl
